Hardware, Embedded Systems "While much of the tech world views a two-year-old smartphone as hopelessly obsolete, large swaths of our transportation and military infrastructure, some modern businesses, and even a few computer programmers rely daily on technology that hasn't been updated for decades." Back when I still worked at a hardware and plumbing store - up until about 4-5 years ago - we used MS-DOS cash registers. They are still in use today. If it works, it works.

Legacy Systems are big business

I work for a company that specialise in maintaining and developing software for legacy systems. These systems are still widely used today, especially in industrial applications such as control systems.

We have customers using equipment from the 1970s, and it's still going strong. The beauty of this hardware is that it is easy to repair. Swapping out burned out resistors or electrolytics on legacy system boards is simple. You just can't do that with today's surface mount, multi layered PCBs.

These systems are still used for the simple reason that it is cheaper to pay a specialist company to maintain the hardware (and software) for the rest of the life of the plant, than it is to develop and commission a replacement system on a modern platform.

Still using my 2007 VIA C7 @ 2 GHz computer running under XP and 2000 without any problem. Without the bloat-ware that is in use nowadays, it's a wonder ! Bloat-ware I say ? Fully configured XP after start : 110 MB RAM used. 2000 ? 56 MB ! Beat this ! Puppy Linux perhaps.

I used to have addiction for Atari computers : ST line with Motorola 68000 @ 8 MHz (yeahs, EIGHT) and 1 to 4 MB RAM, or the Falcon030 with 68030 @ 16 MHz with 14 MB (not 16 due to the IO shadowing, just like a x86 cannot have full 4 GB)

You know what ? These computers used to be just (almost) as usable than an ordinary PC, booted in 30 seconds, lacked a lot of recent ports (USB) and drivers (printers) and also horsepower, but for everyday usage, they were just fine. Now Android device fit the niche : no strong power, but usable.

And the ST manufactured in 1984 were just running as fine as in day 1 ! After more than 30 years ! Just the floppies were shattering into oblivion somedays (wha don't you read stupid plastic disc ?)
